BR
Revision: June 20062007 Versa
Thickness Inspection
1. Using a micrometer, check thickness of disc rotor. If thickness is
outside the standard, replace disc rotor.
2. If runout is still out of the specification, grind rotor with on-car
brake lathe (″MAD, DL-8700″, ″AMMCO 700 and 705″ or equiv-
alent) until runout becomes within the specified limit.
Brake Burnishing ProcedureEFS006JS
Burnish the new braking surfaces according to following procedure after refinishing or replacing disc rotors,
pads, or if a soft pedal occurs at very low mileage.
CAUTION:
Be careful of vehicle speed because brake does not operate easily until pad and disc rotor are
securely fitted.
Only perform this procedure under safe road and traffic conditions. Use extreme caution.
1. Drive vehicle on straight, flat road.
2. Depress brake pedal with the power to stop vehicle within 3 to 5 seconds until the vehicle stops.
3. Drive without depressing brake pedal for a few minutes to cool brake.
4. Repeat steps 1 to 3 until pad and disc rotor are securely fitted.Standard thickness : 24.0 mm (0.945 in)
Repair limit thickness : 22.0 mm (0.866 in)
Maximum uneven wear
(measured at 8 positions): 0.02 mm (0.0008 in)
or less

condition is found, replace it.
Other Inspections
Check the following:
Inside of the drum for excessive wear, damage, and cracks.
Lining for excessive wear, damage, and peeling.
Shoe sliding surface for excessive wear and damage.
Return spring for sagging.
Check back plate for damage, cracks, and deformation. Replace back plate as necessary.
Replace applicable part as necessary.
INSTALLATION
1. If operating lever (C) if removed.
a. Install operating lever (C) to brake shoe.
b. Install retainer ring (A) to operating lever (C), and crimp them
until their contact points (B) are met.

2. Are there any self-diagnostic items, other than those relating to CAN communication system, in the self-
diagnosis results?
If YES, GO TO 3.
If NO, GO TO 4.
3. Based on self-diagnosis results unrelated to CAN communication, carry out the inspection.
4. Malfunctions may be detected in self-diagnosis depending on control units carrying out CAN communica-
tion. Therefore, erase the self-diagnosis results.
5. Diagnose CAN communication system. Refer to LAN-44, "
TROUBLE DIAGNOSIS" .
Precautions for Brake ControlEFS006LA
During ABS operation, the brake pedal may vibrate lightly and a mechanical noise may be heard. This is
normal.
Just after starting the vehicle, the brake pedal may vibrate or motor operating noises may be heard from
engine compartment. This is normal due to the self check operation.
Stopping distance may be longer than that of vehicles without ABS when vehicle drives on rough, gravel,
or snow-covered (fresh, deep snow) roads.
When an error is indicated by ABS or another warning lamp, collect all necessary information from cus-
tomer (what symptoms are present under what conditions) and check for simple causes before starting
diagnosis. Besides electrical system inspection, check brake booster operation, brake fluid level, and fluid
leaks.
If incorrect tire sizes or types are installed on the vehicle or brake pads are not Genuine NISSAN parts,
stopping distance or steering stability may deteriorate.
If there is a radio, antenna or related wiring near the control module, ABS function may have a malfunction
or error.
If aftermarket parts (car stereo, CD player, etc.) have been installed, check for incidents such as harness
pinches, open circuits or improper wiring.
Precautions for CAN SystemEFS006LB
Do not apply voltage of 7.0V or higher to terminal to be measured.
Maximum open terminal voltage of tester in use must be less than 7.0V.
Before checking harnesses, turn ignition switch OFF and disconnect battery negative cable.
Area to be repaired must be soldered and wrapped with tape.
Make sure that fraying of twisted wire is within 110 mm (4.33 in).
Do not make a bypass connection to repaired area. (If the circuit
is bypassed, characteristics of twisted wire will be lost.)
